This species differs from Swertia chinensis Hemsl. et Forbes, 

 which has the taller stem, shorter branches, broader leaves, 

 caeruleo-violaceous flowers, much attenuated sepals, broader and 

 much tapering corolla-segments, and glands incompletely mar- 

 gined with fimbriate hairs. Roots branched, yellowish and 

 strongly bitter.
